【摘要】：以柴达木盆地东部新采集的电磁资料为基础,同时以钻井、地震资料为约束,结合其他勘探资料、重力资料进行柴东地区石炭系综合研究、联合解释。研究过程中,首先对电磁资料进行了前期的预处理和反演,主要采用了一维Bostick反演、一维连续介质反演、二维共轭梯度反演、二维连续介质反演及最优化电性分层等反演技术;而后通过对电磁资料进行联合解释和综合研究,得出了柴达木盆地东部石炭系厚度图、石炭系埋深图等柴东地区综合研究成果;最后利用上述研究成果预测了柴达木盆地东部石炭系含油气有利区带,并且进一步针对柴达木盆地东部石炭系勘探提出了有意义的结论和建议。
[Abstract]:Based on the newly collected electromagnetic data from the eastern Qaidam Basin, and taking drilling and seismic data as constraints, combined with other exploration data and gravity data, the Carboniferous comprehensive study and joint interpretation are carried out in the eastern Qaidam Basin. In the process of the research, the pre-processing and inversion of electromagnetic data are carried out. The inversion techniques such as one-dimensional Bostick inversion, one-dimensional continuum inversion, two-dimensional conjugate gradient inversion, two-dimensional continuum inversion and optimal electrical stratification inversion are used. Then through the joint interpretation and comprehensive study of the electromagnetic data, the comprehensive research results of the eastern part of Qaidam Basin such as Carboniferous thickness map, Carboniferous burial depth map and so on are obtained. Finally, the favorable zones of Carboniferous oil and gas in the eastern Qaidam Basin are predicted by the above research results, and some meaningful conclusions and suggestions for the exploration of the Carboniferous system in the eastern part of the Qaidam Basin are put forward.
